DOOM Eternal
Achievement guide · roadmap · tracker
Doom Eternal is a first-person shooter developed by id Software and the sequel to Doom (2016). Players control the Doom Slayer as he fights to end a demonic invasion of Earth. Combat is built around aggressive resource management, where health, armor, and ammo are gained by executing, igniting, or chainsawing enemies. The game introduces platforming segments, destructible enemy weak points, an expanded weapon arsenal, and a multiplayer mode called Battlemode, where one player-controlled Slayer fights two player-controlled demons.
Two playthroughs are required; the first for all the collectibles and the second in "Extra Life Mode" which is hardcore/permadeath - although you can pick up extra lives as you run through. This is because

Famine mode can be obtained in mission 10. After this mission, use mission select and the cheat menu to enable this cheat- then complete a mission.
This cheat makes enemies not drop any health/armor. They only drop ammo when killed with a chainsaw. Hell on Earth is probably the easiest level to do this on.
Note you cannot get this in Extra Life mode.

Ofc you need to start the game in Extra Life Mode to get this. Make sure you don't die too much... (there are enough extra lives around that you can die a few times though).
This is recommended for a 2nd separate playthrough on the easiest difficulty - although you can do everything all in one run if you really want to.
